Product Details

Description

Ensure your heating system operates safely and efficiently with this premium high limit control switch. Designed as a critical safety mechanism for forced-air furnaces and HVAC units, this thermal sensor monitors the temperature within the heat exchanger. If internal temperatures reach a dangerous level, the switch automatically interrupts the burner circuit to prevent overheating and potential equipment damage. It features a precise 230-degree Fahrenheit cutout point and a 30-degree reset differential to ensure your system returns to operation only when it has cooled to a safe temperature. This 3-inch limit control is a vital replacement part for addressing common furnace issues like short-cycling or a blower motor that runs constantly due to a tripped safety circuit.
